Switch SSSE3 row wrappers from variable sized malloc to fixed size array with… 

Switch SSSE3 row wrappers from variable sized malloc to fixed size array with loop to process a portion of the row at a time.  This helps performance in the case where the image has been coalesced into a single large row and the allocator, although only called once, is slow to clear the pages.  Also the smaller temporary buffer fits cache, further improving performance.
